Characteristics

A tuberous-rooted rhizomatous perennial herb, flowering stem solitary, simple, erect, glandular, thinly cobwebby. Leaves mostly radical, more or less rosetted, up to 100 x 50 mm, elliptic, apex subacute, abruptly narrowed to a broad, clasping, petiole-like base up to 30 x 6 mm, both surfaces glandular-pubescent, stem leaves smaller, narrower, sessile, passing rapidly upwards into distant bracts. Heads homogamous, ±3-4 x 2-3 mm, very many felted together to form very compact corymbose clusters, these further felted together into a flattish disc 20-70 mm across. Involucral bracts in 2-3 series, loosely imbricate, about equalling flowers, not radiating, bright canary-yellow. Receptacle with paleae, equalling the corolla, subtending up to half the flowers. Flowers 7-18, yellow, sometimes tinged red. Achenes 1.25 mm, with myxogenic duplex hairs. Pappus bristles few, slightly shorter than corolla, tips barbellate, bases free.
